Watermelon mosaic virus (WMV) belong to one of the important plant virus genus Potyvirus. This virus has been detected for the first time in 1965 in the Rio Grande Valley of Texas but so far no complete genome of WMV is available from cucurbits in the United States (US). WMV isolate (TX29) was collected from Rio Grande Valley of Texas during a survey in 2010 which showed severe mosaic in a watermelon plant. The complete genome of WMV-TX29 isolate was found to be 10,049 nucleotides excluding the poly-A tail. Nucleotide sequence comparison of TX29 isolate showed more sequence similarities with a WMV-French isolate. This is the first report of the complete genomic sequence of a WMV isolated from cucurbits in the US.
